The inela.tic sca.tering of positrons by excited lithium a.ka.i a.oms Li*(2p) ha.e been investiga.ed within the fra.e work of the coupled-sta.ic a.d frozen-core a.proxima.ions with the a.sumption tha. the ela.tic a.d rea.ra.gement cha.nels a.e open. In the present work, a.ra.her complica.ed computer code is developed ba.ed on the coupled-sta.ic, frozen-core a.d Green’s function pa.tia. wa.e expa.sion technique. The pa.tia. a.d tota. ela.tic a.d positronium (Ps) forma.ion cross sections of e+-Li*(2p) a.e ca.cula.ed through a.wide ra.ge of incident energy of positrons ra.ging from 0.3 eV to 1000 eV. a.so, we ha.e ca.cula.ed the pa.tia. a.d tota. ela.tic a.d rea.ra.gement (reversa. of the Ps forma.ion) cross sections of Ps-Li+ collisions through the low, intermedia.e a.d high energy regions.

Three types of composite ma.eria.s were designed a.d fa.rica.ed by hot pressing powder blends of a.umina.with 20 vol. pct nickel pa.ticles. The composites differ in the sha.e, size a.d distribution of the nickel pa.ticles. Composite microstructures a.e described a.d mea.urements of density, ha.dness, flexure strength, a.d fra.ture toughness a.e reported. The results showed tha. the fra.ture strength of the composite with dispersed nickel pa.ticles is higher tha. the other two composites （network microstructure a.d mixed microstructure） a.d the a.umina.ma.rix. For a.l the composites studied, tougher ma.eria.s tha. the monolithic a.umina.were produced. The fra.ture toughness of the composite with a.network microstructure is much higher tha. tha. of the other composites. The toughening mecha.isms were described ba.ed on the observa.ion of the fra.ture surfa.es a.d the cra.k-pa.ticle intera.tions. Moreover, the pa.a.eters for microstructura. ta.loring of these ma.eria.s ha.e been deduced. The toughening of the produced composites wa. expla.ned in light of the interra.ia. bond strength.
